INK-DISTRIBUTING APPARATUS FOR PRINTING-MACHINES.

SPECIFICATION forming part of Letters Application filed April 21, 1888To all whom it may concern.-

Be it known that I, JOHN T. KING, of Madison, in the county of Dane andState of \Visconsin, have invented certain new and useful Improvementsin Ink-Distributing Apparatus for Printirfg-lvlachines, of which thefollowing is a specification, reference being had to the accompanyingdrawings, in which- Figure 1 is a plan view. Fig. 2 is a section on theline 2 2 of Fig. 1, and Fig. 3 is a section on the line 3 3 of Fig. 1.

My invention relates to ink-distributing apparatus in which a stationaryink-disk and a car traveling over it back and forth are employed todistribute the ink; and it consists in an organization of parts, belowdescribed and claimed.

Referring to the letters upon the drawings, A indicates a car; B, thetracks; 0, the inkdisk; E, the composition rollers; F, the grinding-rollers or screw vibrators, and G the slipnuts, which are pivotedloosely to a shaft, H, so that the screw vibrators will be borne down byforce of gravity upon the upper periphery of the composition rollers.The compositionroller shafts have their bearings in slots I of posts K,secured to the car-frame. The slipnuts engage by their upper surfaceswith the screw-threads on the shaft ends of the screw vibrator. The holethrough the slip-nuts be- Patent N0. 400,223, dated March 26, 1889.

. Serial No. 271,446. (No model.)

ing larger than the diameter of the shaft ends, whenever thelongitudinal movement of the screw vibrator meets with any obstructionthe slip-nuts will rise up slightly, so as to disengage the threads andpermit the rotation of the screw vibrator.

' I do not claim in this application the slipnuts in combination with athreaded shaft and screw vibrator, because I have made that the subjectof a claim in another application-to wit, No. 270,702, filed April 14L,1888; but,

Having described my improvements, what I do claim, and desire to secureby Letters Patent, is- Q The combination, with-a car for anink-distributing apparatus, of the composition rollers, the screwvibrators, I the slip-nuts loosely pivoted to the shaft 1., so as tocause the screw vibrators to bear by the yielding force of gravity uponthe upper peripheries of the composition rollers, subs antially as setforth. 4

In testimony of all which I ave hereunto subscribed my name. i

JOHN '1. KING.
